[PATCH 12/12] tools: Correct redundant test

[Julia Lawall]

From: Julia Lawall <julia@xxxxxxx>

symstrs has already been tested.  It seems that this test should be on the
recently returned value secstrs.

A simplified version of the semantic match that finds this problem is as
follows: (http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
local idexpression x;
expression E;
@@

if (x == NULL || ...) { ... when forall
   return ...; }
... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\)
(
*x == NULL
|
*x != NULL
)
// </smpl>
